--To allwhomit cmm.-

Be it knc am that I, PHILIP C. BONNER, 'a

subject of the Emperor of Germany, residing at Summit, in'the-county of Union and State of New Jersey, have invented certain new and useful Improvements in-Ap aratus for Drying, Baking, qr Roasting; and I do hereby declare the following to be .a full, cl ar, and exact description of the invention, suc as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to, letters of reference marked thereon,

- which form a part of this specification.

The present invention has reference, gen- --erally, ;.to that class of apparatus which are usedmore particularly for drying purposes but which under certain conditions maybd employed also for baking or roasting puroses. p This invention relates, more especially, to a noveldevice or ap aratuswhich is to be used rincipally for .t e drying of furs, skins, and t e like; but which may be'used also in the manner of a bakers oven, for baking and .other kindred pur oses.

The invention as for its principal object to provide a simple and efficiently operatingdevice of the general character hereinafter more fully set forth, in which the article or material which is to be dried or baked, as the case may be, is fed atone side into a heated receptacle or chamber, traveling through the said receptacle or chamber at a rate which will thoroughly dry or bake the article or material, and then passing in its dried or baked condition from the opposite side of the receptacle or chamber.

-A further object of this invention is to provide a novel feeding device or carrier upon which thearticles or the materials which are to be'dried o r baked, are placed, and caused to move between a s stem of heat-conveying pipes or ducts, so t at the heat will be applied directly u on-all sides of the article or material,- and t e conveyer or carrier being provided with suitable openings throug which the heat readily passes, said conveyer being usually. of a wire-woven mesh, or a wire-belt ofany suitable construction.

Other objects of this invention not at this atime. more particularly mentioned will be i tailed description of the same.

clearly understood from the following de- With the various objects of my present in-- vention in view, the invention consists, primarily, in the novel drying orbakmg appara- 1 tus hereinafter set forth ;and, furthermore,

this invention consists in the novel arra e-V ments and. combinations of the various vices andv arts, as well as m the details of the construction of the same, all of which will be hereinafter, more fully described and then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, "in which: Figure 1 is an elevation of the one side of the device or apparatus; and Fig. 2 is a similar view of the opposite side of the apparatus. Fig. 3 is a longitudinal vertical sectional representa tion of the receptacle or chamber, and the variously arranged and laterally extending shafts therein, said view. showin also in side elevation, the arrangement of t e'conveyer or carrier, and the systems of heating coils or pipes disposed upon the opposite sides of the conveyer .or carrier. Fig. 4 isa hor zontal sectional representation of the rece tacle or chamber, the conveyer orcarrier, t e mech anism for operating the belt,-and the upper. I svstem of heating coils or pipes, all being shown in plan or top.view;and Fig. 5 is a detail horizontal sectional re resentation of the receptacle or chamber,'s o'adng in connection therewith, and in plan or top view, an

arrangement of the lower system, of heating pipes, and the various shafts with their ratchet-wheels and feed-rollers.or ulleys, -the conveyer or carrier and the mec amsm for operating the same being omittedfrom the view.

Similar characters of referenceare em'-':

loyed in all of the various fi es of the drawings, to indicate correspon mg parts.

Referrm now to the several figures of the drawings, t e reference-character 1 ind cates the complete apparatus or device embodying the rinciples of this invention and to be use for dl-ying or baking purposes, said apparatus consisting, usually a longrece tacle or chamber, built of O rick or any suita le material, andpcomprising the-two sides 2 and 3,

the front end 4 which is provided with a pair of openings 5 and 6, and the rear end 7 made withv openings- 8 and 9. I receptacle,- chamber or, compartment,'is closed at the top with a series of 'removably arran ed iron or other suitable doors or covers 10, w ich are preferably sheathed with asbestos layers 11.

At one end of said receptacle, as at its rear end, and situated upon the outside of the apand in mesh with said gear is a pinion 22 which is secured upon a main driving shaft 23, rotatably arranged in the bearings 24 of a pair of pedestals 25 which are suitably secured u on supports or brackets 26 at the side of t e a paratus,substantially as shown. Upon said s raft 23 is a loosepulley 27 and a fast pulley 28, driving a nelt 29 passing over said loose pulley and being adapted to be shifted from said loose pulley upon the fast pulley by meansof a belt-shifter '30, which extends along the outer side of'the ap aratus toward the front end of the same, an is provided at said end with a suitable operating handle or member 31.

At the front end of the'apparatus is a suitable arrangemcnt of supports or brackets 32, each support having suitably secured to its side, by means of bolts-or screws 33, a plate 34. Each plate is made with a longitudinally extending opening 35, and guides 36, between which are slidably arranged suitable bearing-blocks 37, carrying a laterally extending shaft .38. Connected with each bearing-block 37 is a hub 39 to which is rotatably attached the end-portion of an adjusting screw 40. Each screw 40 extends through a screw-threaded boss 41 at the side of each plate 34, and 42 is a finger-piece or handwheel for making the desired adjustments of the nearing-boxes or block 37 and the shaft which is mounted in said hearing, as will be clearly evident.

Suitably dis osed upon the she. t 15 are a series of sproc et-wheels 42, and upon the shaft 38 are correspondingly arranged sprocket-wheels 43, suitable link-chains 44 passing over each pair of s rocket-u heels 42,

and 43, the chains passing cm the wheel 41 through the opening 5 into the interior of the apparatus, then out of the opening 8 and over the wheel 43, returning through the opening 9 into the chamber, and then out of t e opening 6 back upon the wheel 42, as clear] indicated in Fig. 3 of the drawings. Within the interior or chambered portion of the apparatus are other shafts 45 rotatably arranged in bearings 46, each shaft 45 carrying correspondingly arranged sprocket-wheels 47 upon which the upper pr inwardly moving portions "of the linkchains are operatively supported, the lower or returning or outwardly moving portions of the link-chains being in rolling contact with suitably disposed rollers 48, arranged upon another set of shafts 49 rotatably arranged in suitable bearings 50, placed lower down within the drying or baking chamber, as will be clearly understood from an inspection of the figures of the drawings.

A suitably constructed conveyer, apron, or carrier-belt 51 is suitably secured to the said link-chains in such a manner that when the said link-chains are operated, the said belt or conveyer will move throu h the chamber of the apparatus, as will be 0 early understood. The belt, conveyer or carrier, as has been stated, is preferably provided with variously disposed and numerous openings, one preferred construction being a conveyer or carrier made of a wire-woven fabric.

One means of heating the interior of the i The reference-character 52 indicates an inlet-pipe, which is connected with a manifold 53 extending across the rear of the ap paratus; Within the chamber of the apparatus, extending longitudinally and adjacent to the inner side of each wall 2 and 3 are pipes or manifolds 54 and 55, respectively, and as shown more especially inFig. 4 of the drawin s, the pipe or manifold 54 being connected y means of a pipe 55 with the manifold 53. Extendin from one end of the pipe or manifold 55 is a s ort pipe 57 which is connected with a manifold 58 extending laterally across and upon the outside of the front 4 of the apparatus, an outletipe or exhaust 59 leading from said manifol 58. Connecting pipes or coils 60 are arranged between the i es or manifolds 5 4 and 55, so as to establis communication between the latter, said conveyer or carrier, substantially as illustrate Referring now more articularly to Fig. 5 of the drawings, it will e seen that there are a series of short pi cs 61 which extend from the manifold 53, through the rear 'wall 7-of the apparatus, said pipes 61 beinglconnected with manifolds 62 arranged against the inner face of said wall 7. In a like manner, a se ries of short pi es 63 extend from the manifold 58, throng the front wall 4 of the apparatus, said pipes 63 being connected with manifolds 64 which are arranged against the face of said wall 4. A series of connectin ipes 65 are arranged between the severa manifolds 62 and 64', substantially in the manner illustrated in said Fig. 5 of the drawings. From an inspection of Fig. 3 of the drawings, it will be seen, that the pipes 65 pipes or coils 60 being arranged above the are arranged beneath the upper or inwardly moving portion of the conveyor or carrier.

Referring again to Fig. 3 of the drawings, it will be seenthat the various heat-convey ipes and coils, preferably pitch downwar y from the rear of back to the forward end of the chamber of the apparatus, the contop of each other,

v'eyer or belt moving slowly between the upper and lower sets of heaters, from the low end of the chamber to the high end of the same, and the belt being of an open mesh it enables, in practice, to arrangetwo skins on with the hide-sides to- "gather, so that the respective fur-sides of the skins will always be nearest the upper and lower heating devices, or heating pipes and their coils, thereby doubling the capacity of the ap aratus. This is also of great advantage. w en the apparatus to be used for baking our oses, as thereby theloaves of dough whicare placed'upon the conveyor or belt, are subjected to the heat on 'top and bottom, as well as upon their sides. L

The operation of the apparatus for drying, baking or roasting urposes, is very simple.

It will easily be on erstood'from an inspection of the drawings, as briefly is as follows:After-the conveyer-rnechanism has degree of heat, the skins, or other matter to be treated, are placed in the manner. previ- Ously stated upon the upper moving portion of-the conveyor, dirr ctly-in front of the opening or inlet 5 in the front wall 4. The skins,

or other matter, are then slowly carried 40 rear finally emerging through the o enin 8 irilhe rear wall 7 in a perfectly driedfiu ke through the heated chamber, from front to oi roasted condition, according to the uses v to which the apparatus is put, the articles being removed rom the conveyer by an operator at the rear of the apparatus. From the foregoing descri tion of my resent invention it will be 0 early seen, t atI have devised a simply constructed and efficiently operating apparatus or device, in which the capacity of t e work performed can be dou bred, and in which a continuous drying, bakor roasting process is maintained. clannz- 1.
